ive been using this alarm clock for about 10 days and it has changed my morning life. I wake up happier and the monitoring of my sleep is a huge perk to understanding my daily productivity levels in my work. The sound is amazing and awaking to the sounds of the waves is perfect. If you have concerns or curiousity about your sleep patterns i recommend this product to you. Im a stickler for the details and this product is a must have.........
